danah boyd, a leading social media expert and researcher at Microsoft, studied how teenagers use social networks. She discovered that teens create a "digital body" to represent themselves online and spend time curating their profiles to reflect their real identities. The wall or comments section is crucial for maintaining friendships, serving as a public display of connection. Teens mostly use social media to interact with existing friends, often due to busy schedules, parental restrictions, or long distances. danah also explored teens' growing awareness of online privacy and visibility, noting examples like parents discovering unexpected behavior through tagged photos. As teens grow older, their online habits may change—something danah continues to explore.
